Specification of Letters Patent.

Patented Apr. 13, 1915.

Application filed september 30, 1907. Serial No. 395,119.

To all whom it may concern Be it known that I, Josnrn ToMmNsoN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in WrapfpingMachines, of which the following is a ull, clear, and exact specification.

This invention relates to machines for wrapping magazines, books, pamphlets, and other articles of similar shape or form capable of being storedin regular formation in a suitable hopper or magazine, from which they may be extracted separately, and the invention has for its primary object to provide improved and efficient means whereby the magazines or articles may be quickly and accurately extracted one at a time from the general supply without disturbing the balance of the supply, and then inserted and enfolded in a suitable wrapper which is subsequently and automatically pasted together where it overlaps, the wrapper "being either previously or subsequently addressed, if necessary.

With a view to the attainment of these ends and the accomplishment of certain other objects, which will hereinafter appear, the invention consists in the features of novelty which will now be described with reference to the accompanying drawings, and then more particularly pointed out in the claim.

In the said drawings-Figure 1 is a side elevation of a wrapping machine embodying this invention. Fig. 2 is a view similar to Fig. 1, partly in vertical section and partly broken-away- Fig. 3 is a top plan view. Fig. 4: is a sectional view on line 1 1 of Fig. 2. Fig. 5 is an end View of the hopper and the yielding extension lip. Fig. 6 is a detail perspective view of the ejector. Fig. 7 is a detail perspective view of the yielding extension lip. Fig. 8 is an enlarged detail section of the lower end of the feed hopper, showing also some of themagazines.

The magazines or other articles which are indicated at 1 are placed on edge upon the inclined bottom 2 of a suitable hopper, and rest directly upon the upper fold of one or more endless belts or tapes 3 which may be driven continuously in a downward direction over suitable pulleys t, 5, having any appropriate operative relation to some moving part of the mechanism, such, for instance, as a belt 5 driven from one of the cutting rolls hereinafter described, which in turn is driven by the belt 5" which receives motion from one of the extracting rolls, also hereinafter described, whereby the inagazines or articles 1 are given a continual tendency to feed downwardly against the inner face of an ejector or plunger 6, so that the instant the end magazine is removed, the entire supply will advance, bringing the next one into its place directly against the ejector. This ejector is mounted to move preferably in a vertical direction in suitable end guides 7, which are provided with grooves 8, receiving tongues 9 on the plunger or ejector 6, or these parts in lieu of such grooves and tongues may be given any other suitable guiding provisions. The ejector receives its up and down movement from an arm 10 on a bell crank lever pivoted at 11 and having its other arm 12 connected to some part of the machine, such for instance as a pivoted arm 12, by the rod 13, and the arm 12 may be provided with a forked extremity 12 within which an eccentric 12 operates to oscillate the arm; the eccentric being secured to a driving shaft 12, which latter may be.oper ated in any desired manner.

' The inner side of the plunger 6 is provided with an ,ofiset forming an ejecting shouldei- 1 1, andwhereby such inner side is dividedinto two faces set in different vertical planes. The upper one of these is indicated at 15 and the lower one at 16, and it will be seen that while the shoulder 14 and the lower face 16 are cooperating to eject the end magazine, the face 15 is serving as a stop for the next magazine and holds back the main supply while the end one is being forced downwardly. The range of movement of the plunger 6 is such that when at the upper limit of its stroke, the shoulder 14 will rise above the upper edge of the lowermost or end magazine, whereupon the feeding tendency exerted by the belt or tapes 3 will at once introduce the end ma az'ine under such shoulder in position to be e ected. The plunger then moves downwardly and carries the end magazine into the grasp of mechanism which will be presently described, for enfolding it in the wrapper. As the end magazine moves into position'below the shoulder 14, it is temporarily supported by a yieldin extension or lip 17 on the lower end 0 the hopper bottom 2. This lip or extension is pivotally mounted on a crossshaftor rod 18 and is provided with an arm 19, to which is attached a spring 20,

serving to hold the lip normally elevated with its upper edge or face flush with the surface of the bottom 2, the latter being extended, as more clearly shown'in Fig.8, to

a point Where it will unyieldingly hold the next magazine from being moved down wardly by frictional contact with the one being ejected. lVhen the end magazine receives the pressure of the ejecting shoulder, however, the spring supported lip 17 yields and permits it to pass through a slot 21 in a table 22 and across which slot projects the wrapper 23. When the magazine iasses through the slot, it of course carries the wrapper with it, and as it descends it comes into the grasp of a pair of feed rolls 24:, 25, which finish the extraction 1 of the magazine from its position between the face 16 of the plunger and the remaining supply of magazines and introduce the magazine and wrapper together into one of a series of pockets which first undergo a receding or reciprocating movement, and then a rotary movement for the purpose of carrying the partially wrapped magazines away from the rolls 24, 25, and finishing the wrapping and sealing operation and then delivering the downwardly by the rolls 24-, 25, the series of pockets is in the position indicated in Fig, 2, with one pair of the jaws 26 in close proximity to. the rolls 24, 25, and preferably in between them, so as to surely receive the descending magazine. The series of pockets then undergo a downward movement of sufficient extent to enable the jaws 26 to clear the rolls 24., 25, whereupon the series of pockets receives a rotary motion which is preferably of an intermittent character, causing the pocket which has just received the magazine to move toward the left, as shown in Fig. 2, and to bring another pocket into position directly beneath the space between the feed rolls 24, 25 to receive the next magazine, the magazine previously received in the meanwhile having been carried into a position adjacent to a curved deflecting plate 28, against which the upper projecting end of the wrapper engages and is thereby caused to partially fold toward the other extremity of the wrapper, where it is to be eventually sealed, the deflector 28 also serving as a means of preventing the premature other one, preferably one which is diametrically opposite the one which is receiving, is directly opposite the space between a pairof extracting rolls 29, 30, so thatwhen the series of pockets makesits downward bodily movement, the projecting end of the magazine in the pocket which is opposite the rolls 29, 30, will be introduced into the grasp of these rolls and thereby pulled out of the pocket, and the lower or free end of the wrapper will be rolled or pressed firmly against the side of the magazine and over-the other end of the wrapper, which has'previously received paste. Hence it will be seen that this operation in which the rolls 29, 30, take part, not only serves to relieve the jaws 26 of the magazine and wrapper, but also to seal the flap of the wrapper in place.

The wrappers 23 may be fed into the machine in any suitable way, either singly, or in continuous form, as desired. In this example of the invention is illustrated a roll of paper 31, which is first fed between cutting or perforating rolls 32, serving to partially sever the strip of paper so that it may be subsequently pulled apart into the form of separate wrappers while passing between two pairs of rolls 33, 34-, the latter of which may be driven at a higher rate of speed than the former, whereby they will tear the wrappers apart and then feed them across the slot 21 in the table, the latter being provided with a gage or stop 35 at the proper point for positioning the wrapper under the plunger or ejector.

The roll 24 is provided with a paste pad 36, which is supplied with paste from a paste fountain 37 by a ductor roll 38 oscillated between the roll of the paste fountain and the roll 24, in any suitable manner such for instance as by means of a rod 38 connected to the roller support 38 and the arm 12*, and being so timed with relation to the rotation of the roll 24 that the pad 36 will be in position to receive paste from the ductor roll 38 when the latter' reaches the peripheral line of the roll 24, and the roll 21 is so roportioned and timed with relation to the size of the wrapper and its movement that the pad. 36 will contact only with the short end of the wrapper, or, if desired, with the short end of the wrapper and a small portion of the body of the magazine, and consequently will not come in contact with the magazine or Wrapper at any other point.

The before mentioned bodily reciprocating and rotary movement of the drum 27 may be imparted thereto by any suitable means. For that purpose I have shown the memory shaft 39 of the drum provided with a ratchet wheel 40 secured rigidly to oneend thereof and arranged to be engaged on one side by a spring pressed retaining pawl 41, mounted on a suitable support 43 which is movable with the bodily movement of the drum and shaft, and on the other side by a spring pressed arm 42, having a straight edge or fiat face 42 and a shoulder 42 adapted to engage the ratchet to rotate the shaft 39. The arm 42 is pivoted to any suitable fixed support with reference to which the shaft 39 moves vertically, and. is pressed normally by a spring 44 against the face of the ratchet. The ratchet has as many teeth as there are pockets 26 in the drum, and it will be seen that as the shaft 39 descends one of the teeth is engaged by the shoulder 42 on I the arm 42 and the shaft thereby rotated,

and when the shaft rises two of the teeth of the ratchet will engage the straight edge or flat face 42 of the arm 42 to prevent rotation of-the drum. In this position, one of the pockets is directly inline with the path of the magazine as it descends from the rolls 24, 25. 'When the drum again moves downwardly, the straight edge of the arm 42, by pressing against two of the teeth at one ti1ne,holds the drum against rotary motion, until the'tooth of the ratchet engages the shoulder 42 when it will be rotated another step and is held against retrograde movement by the pawl 41. The shaft 39 of the drum may be mounted in suitable sliding boxes and may be given this rising and falling motion by oscillating arms 45 mounted upon rocker shaft 46 having a crank arm 47 connected by a rod 48. to any suitable moving part of the mechanism, such for instance as an eccentric 48 on the shaft 12 properly timed with relation to the plunger 6, rolls 24, 25, 29 and 30, and the arm 38", which carries the ductor roll.

The rolls 29-30 may be geared together and may receive motion from a suitable gear 50 on the'shaft 12 and an intermediate gear 51 which will impart motion to the belt 5". Motion may also be imparted'to the rolls 24, 25, which latter may be geared together, by means of gears 24225 through the medium of an intermediate gear 52, engaging the gear 50 and the gear on one of the rollers and an intermediate gear 53 may be provided for operating the rolls 34 from one of the feeding rolls through the medium of gears 34. Likewise a gear 54 may be provided for operating the rolls 33 from-the rolls 32, through the gears33 and motion may be imparted to the paste roll 37 by means of a belt 37 driven from the shaft 12. Obviously any suitable mechanism may be employed for operating the parts in unison as this forms no part of the invention.

Having thus described my invention, what ll claim as new and desire to secure by Letters Patent is:

The combination with a hopper having a narrow opening in its bottom adjacent one of its terminals; a spring pressed stop pivoted to said hopper fitting said narrow opening and having its upper surface coplaner with the upper surface of the bottom of the hopper; and an ejector operating across one terminal of said hopper, there being a portion of said ejector-adapted to move by one edge of said stop and cooperate therewith to guide an article from said hopper and another portion of said ejector disposed above said stop and adapted upon movement toward the latter to move an article in said hopper through said narrow opening and swing said stop out of the latter.

in testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 7th day ofSeptember, A. l). 1907.
